a) Please provide the maximum length and height of the high wall that will be in place at any <br />given time that will require the slopes to be cut from the mining slopes of 1.5:1 to post mining <br />slopes of 3:1, as proposed. The only reference to the maximum lineal feet of high wall is <br />mentioned in exhibit "L" reclamation cost estimate, where 400 lineal feet of high wall <br />reduction cost was used to calculate the reclamation warranty. <br />The maximum length will be four hundred (400) feet and the maximum height will be <br />between 20 feet and 25 feet depending upon the location along the wall. Please see the revised <br />Mining Plan Map for the predicted location in the west end of Phase One (1). This is the area used <br />to estimate the reclamation cost shown on Exhibit "L". <br />6.4.4 Exhibit "E" Reclamation Plan <br />1. The operator is committed to cutting all high wall slopes to at least 3:1 as part of the final <br />reclamation for the pit. An average of 10 inches of growth medium is proposed to be placed <br />throughout the affected area, with 401bs/acre of fertilizer. Seed mix is in accordance with the <br />recommendation of the local soil conservation district. A noxious weed control plan is in place. <br />The Division recommends all available top soil should be salvaged and placed throughout the <br />affected area. Where is the location of the top soil stockpile in any of the maps? Please provide <br />the location of the stockpiles that will be placed within each phase, in both the mining and <br />reclamation maps. <br />The applicant has revised the Mining Plan Map in-oder to show the growth <br />medium (aka topsoil) stockpiles. Each Phase will have separate stockpiles to <br />facilitate the placement for each area without moving a long distance for cost <br />savings and ease of placement. The stockpiles are also placed up hill from the area <br />that will be seeded again to make the moving of the growth medium soil stockpiles <br />extremely efficient. Please see the revised Mining Plan Map. The Reclamation <br />Map was not used to show the growth medium soil stockpiles for clarity of <br />presentation. The stockpiles will be gone after the reclamation of the lands and <br />will not remain post mining. <br />6.4.7 Exhibit "G" Water Information. <br />1. Under the exhibit, the operator states" If ground water is encountered, the Division will be <br />notified and mining operations will be adjusted accordingly. The operation might affect surface <br />water during high precipitation. Please refer to Exhibit "C" mining map and Exhibit "F" <br />reclamation map for information and locations and details of earthen berms and surface water <br />drainage". The Division cannot find the information mentioned in your narrative in both <br />Exhibits. Please provide details of these structures, as mentioned in your narrative. <br />2. However, there are what appeared to be two ephemeral channels that feed what appeared to <br />be two stock ponds in the mining and reclamation plan maps. Both these ponds have the <br />potential to be impacted by the proposed mining activity. The stock pond located along the <br />south western side (in the area labeled as mining area buffer zone) appeared to be outside of <br />the proposed permit area. However the drainage channel feeding this pond is going to be <br />impacted by the proposed mining activity. Please explain how you plan to mitigate impacts to <br />these ponds and the drainage channels.
